Title: Image forming device
Inventor: YAMAGUCHI TADAYOSHI
IPC: G03G15/00
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device where dust or dirt adhering to the surface of a reflection mirror is removed every time image forming operation is performed and which has excellent serviceability and maintainability. SOLUTION: A brush-like cleaning part 36 having a brush whose edge part is curved is attachably/detachably installed on an inner cover 34 out of an effective image area below a housing 12 adjacent to a contact glass 10. Since the cleaning part 36 is positioned in parallel with the 1st reflection mirror 18 on the traveling path of a 1st traveling body 20 on which the mirror 18 is mounted, the curved edge of the brush of the cleaning part 36 comes in contact with the surface of the mirror 18 so as to sweep the surface of the mirror 18 like a broom every time the traveling body 20 travels, that is, every time copying operation is performed by a digital copying machine. Thus, the dust adhering to the surface of the mirror 18 is easily removed.

The outputs Vs and Vs' are determined to show nearly a straight-line relationship with a distance at a specified distance range and the ratio is equal to a contact ration m. The output Vs which is amplified by coefficients r1 and r2 which are in a relationship r1 < m < r2 at amplifiers 15 and 16 is fed to comparators 17 and 18 along with the output Vs' and the output is supplied to a switch SW through an AND gate 19. Then, when a position of a target object 3 is proper, a ratio of the output Vs to the output Vs' is nearly equal to a constant ratio m so that the SW is closed and the output Vs is output. On the other hand, when the object 3 is not located properly, no output Vs is output.
